実験手順: Example 54 was synthesized in 4 steps from 3-,5-dibromophenol. 2-Methoxy-5-fluorophenyl boronic acid was reacted as described above, step 1. In this manner was isolated 5-bromo-5′-fluoro-2′-methoxy-biphenyl-3-ol, which was then reacted with 3-fluorophenyl boronic reacted as described above, Step 2. In this manner, 3,5″-difluoro-2″-methoxy-[1,1′;3′,1″]terphenyl-5′-ol was obtained.

実験手順: To a stirred mixture of 4-(6-chloro-pyrimidin-4-ylcarbamoyl)-piperidine-1-carboxylic acid benzyl ester (VIII) (0.60 g, 1.6 mmol) and 5-fluoro-2-methoxy-phenylboronic acid (0.300 g, 1.76 mmol) in saturated sodium carbonate solution (5 ml) and 1,4-dioxane (5 ml) was added palladium(II) acetate (0.072 g, 0.32 mmol) followed by triphenylphosphine (0.084 g, 0.32 mmol) at room temperature under an atmosphere of nitrogen. The resulting mixture was heated to reflux at 110° C. for one hour and the reaction monitored by TLC. The reaction mixture was filtered through a celite bed and the filtrate was extracted with ethyl acetate (3×100 ml). The organic layers were separated, combined, dried over sodium sulfate and concentrated under reduced pressure. The crude product was purified by flash column chromatography (silica gel, elution with 50% ethyl acetate/n-hexanes) to afford 4-[6-(5-fluoro-2-methoxy-phenyl)-pyrimidin-4-ylcarbamoyl]-piperidine-1-carboxylic acid benzyl ester (XXI) (0.39 g, 52%) as a pale yellow oil. The resulting mixture was heated The reaction mixture was filtered through a celite bed the filtrate was extracted with ethyl acetate (3×100 ml) The organic layers were separated dried over sodium sulfate concentrated under reduced pressure The crude product was purified by flash column chromatography (silica gel, elution with 50% ethyl acetate/n-hexanes)
